In his teaching, Prof. Arka Mandal strives to break down fundamental concepts to the greatest possible extent, to help students understand why they study what they study.
Courses taught: Diffusion and Kinetics (PG)
Courses to be taught: Principles of Crystallographic Texture (UG/PG), Thermomechanical Processing and Forming of Steel (UG/PG)
Prof. Arka Mandal's research focuses on the deformation behaviour of metallic materials across length scales, from bulk response to nanoindentation, with emphasis on crystalline defects [1], solid-state phase transformations, and the processing-structure-texture-property correlation in steels. He employs advanced electron microscopy and related characterization techniques [2] to reveal the role of defects, interfaces, and microstructural evolution in governing mechanical behaviour. His work integrates experimental analysis with a fundamental understanding of deformation and transformation mechanisms to build structure-sensitive insights for metallic systems. A strong focus of his research is on steels, where texture evolution [3] and phase stability are linked to performance under service conditions. Overall, his research aims to connect microstructural features with macroscopic properties for the design of stronger, more reliable engineering materials.

φ2 = 0°, 45°, and 65° sections of the orientation distribution function of FCC-austenite in strain-free, 0.05 strained (simulated), 0.1 strained (simulated), and 0.2 strained (simulated and experimentally obtained) conditions. Simulation is done in VPSC.
